Description

Technical Field

[0001] This utility model relates to the field of clothing recycling technology, and in particular to a conveying and handling clamp. Background Technology

[0002] In modern logistics, warehousing, and production lines, turnover boxes serve as the core carriers of materials, and the flexibility, efficiency, and reliability of their handling directly determine the effectiveness of the entire system. Currently, the path changes and position adjustments of turnover boxes in automated conveying processes heavily rely on a complex system composed of fixed equipment, such as elevators for changing height, inclined conveyors for achieving tilted conveying, and transfer machines and right-angle turning machines for changing conveying routes.

[0003] This traditional model suffers from inherent technological bottlenecks, stemming from the lack of a dedicated, intelligent, and efficient handling fixture capable of deep integration with flexible actuators such as robots. Specifically: 1. The system has extremely poor flexibility and severely insufficient spatial freedom: The movement of the turnover box is restricted by a pre-set mechanical track, allowing only fixed, linear path movement. It cannot achieve precise positioning and posture adjustment at any point in three-dimensional space like a robot, making it difficult to adapt to the demands of modern flexible manufacturing with its ever-changing layouts and complex processes.

[0004] 2. Slow overall cycle time and low efficiency: The entire handling process requires multiple machines to work in relay, and each step involves time consumption for acceleration, deceleration, and waiting. The action chain is long and complex, causing the overall cycle time of the system to be limited by the slowest link, making it impossible to meet the requirements of high-efficiency and fast-response production cycle time.

[0005] 3. Poor positioning accuracy and stability: During the transfer and turning process involving multiple devices, the turnover boxes are prone to cumulative positional errors and attitude deviations. More importantly, under heavy load conditions, traditional conveying methods lack active clamping and support mechanisms, posing a risk of box slippage or overturning due to inertia or vibration, resulting in insufficient safety and reliability.

[0006] 4. Poor adaptability and lack of versatility: Existing systems are usually designed for turnover boxes of specific sizes. Once the specifications of the box (such as width and height) change, the entire conveyor line often needs to undergo heavy mechanical adjustments or program resetting, or may even be incompatible, resulting in high modification costs, long downtime, and low flexibility.

[0007] Although the concept of combining turnover boxes with robots has emerged in the industry, the robot's spatial freedom advantage cannot be fully utilized without a dedicated gripper designed specifically for turnover boxes. Ordinary grippers are often limited in function, either only providing lateral gripping without bottom support, posing a risk of falling off during rapid movement or under heavy loads; or they cannot adapt to changes in the size of the box, greatly limiting the robot's application potential.

[0008] Therefore, there is an urgent need for a new type of turnover box handling fixture that can achieve fast, safe, adaptive operation and seamless integration with robotic systems. Summary of the Invention

[0009] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a conveying and handling clamp that can accurately clamp the box and improve reliability during movement.

A first connecting rod is connected between the upper ends of the two first connecting plates, and the two ends of the first connecting rod are connected to the upper part of the support frame through bearing seats.

[0014] In some embodiments of this utility model, the inner clamping assembly includes: Side clamping plate; There are two main connecting plates, the lower parts of which are connected to the side clamping plates; the middle parts of which are hinged to the support frame. In this configuration, all the main connecting plates in the two inner clamping assemblies are connected to the inner drive mechanism.

[0015] In some embodiments of this utility model, a second connecting rod is also connected to the middle of the two main connecting plates in the inner clamping assembly. The second connecting rod is rotatably mounted on the support frame. Auxiliary connecting plates are symmetrically arranged on both sides of the two main connecting plates. The upper ends of the two auxiliary connecting plates are connected to the second connecting rod, and the lower ends of the two auxiliary connecting plates are connected to the side clamping plate.

[0016] In some embodiments of this utility model, the external drive mechanism includes: First cylinder; The second cylinder is arranged parallel to the first cylinder and installed in the opposite direction; Wherein, the fixed end of the first cylinder is connected to the middle of the first external clamping assembly of the two external clamping assemblies, and the telescopic end is connected to the middle of the second external clamping assembly of the two external clamping assemblies; the fixed end of the second cylinder is connected to the middle of the second external clamping assembly, and the telescopic end is connected to the middle of the first external clamping assembly.

[0017] In some embodiments of this utility model, a first synchronization mechanism is further included, the first synchronization mechanism comprising: A synchronization plate is disposed in the middle of the support frame and above the external drive mechanism; The first synchronizing rod has one end hinged to one end of the synchronizing plate and the other end connected to the upper part of the second external clamping assembly. The second synchronizing rod has one end hinged to the other end of the synchronizing plate, and the other end connected to the upper part of the first external clamping assembly. The support frame has a central shaft at its bottom, and the synchronization plate is rotatably mounted on the central shaft.

[0018] In some embodiments of this utility model, the internal drive mechanism includes: The third cylinder, The fourth cylinder is arranged in parallel with the third cylinder and installed in the opposite direction; The third link, the two ends of which are respectively connected to the fixed end of the third cylinder and the telescopic end of the fourth cylinder; The fourth link, the two ends of which are respectively connected to the fixed end of the fourth cylinder and the telescopic end of the third cylinder; The third link and the fourth link are respectively connected to the inner clamping assembly on the same side.

[0020] According to an embodiment of the present invention, a conveying and handling fixture, through the coordinated design of a support frame, an outer clamping mechanism, an inner clamping mechanism, an outer drive mechanism, and an inner drive mechanism, has the following main advantages: First, it achieves extremely high spatial freedom and motion flexibility: This fixture can be deeply integrated with flexible actuators such as industrial robots, breaking through the physical constraints of traditional fixed conveyor lines. This enables the turnover box to move along arbitrary trajectories, be precisely positioned, and have its posture adjusted (such as lifting and rotating) in three-dimensional space, perfectly adapting to modern flexible manufacturing scenarios with complex and ever-changing layouts and flexible processes.

[0021] Secondly, it significantly improves handling efficiency and system cycle time: By using a robot in conjunction with this fixture, complex actions that previously required multiple devices to work together (such as lifting, transferring, and turning) are integrated into a continuous and smooth single action. This greatly shortens the process chain, eliminates waiting time between devices, and achieves a leapfrog improvement in handling cycle time, meeting the demands of high-efficiency and fast-response production.

[0022] Third, it significantly enhances the stability, accuracy, and safety of handling: The combined handling method of "side clamping and bottom support" ensures the stability and safety of the turnover boxes, especially those with large loads, during high-speed operation and changes in posture. The lateral clamping force effectively overcomes inertia and prevents slippage; the bottom support fundamentally eliminates the risk of tipping over and falling, thus achieving extremely high positioning accuracy and handling reliability.

[0023] Fourth, it possesses excellent adaptability and versatility, with a high degree of flexibility: By employing adjustable-stroke cylinders and corresponding adjustable support mechanisms, this fixture can quickly adapt to turnover boxes of different widths and heights, achieving compatibility of a single fixture with multiple box specifications. This greatly reduces equipment adjustment time and modification costs caused by product changeovers, improving equipment utilization and the flexibility of the production line.

[0024] Fifth, the system structure is optimized, reducing overall costs: The application of this fixture can replace or reduce the use of various specialized equipment such as hoists, transfer machines, and right-angle turning machines, simplifying the layout of the entire conveying system and saving equipment floor space and initial investment. At the same time, its high reliability and versatility also reduce subsequent maintenance costs and downtime losses. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is for reference. Figures 1-12 The conveying and handling fixture 100 according to an embodiment of the present invention includes a support frame 10, an outer clamping mechanism, an inner clamping mechanism, an outer drive mechanism 40, and an inner drive mechanism 50. The outer clamping mechanism includes two outer clamping assemblies 20, which are symmetrically arranged on both sides of the support frame 10 and rotatably mounted on the support frame 10 to provide bottom support force to the box 300 to be transported. The inner clamping mechanism includes two inner clamping assemblies 30, which are symmetrically arranged on both sides of the support frame 10 and rotatably mounted on the support frame 10. Located inside the outer clamping mechanism, it is used to provide lateral clamping force to both sides of the housing 300; the outer drive mechanism 40 is installed inside the support frame 10 and is connected to the middle of the outer clamping mechanism to achieve clamping or releasing of the housing 300; the inner drive mechanism 50 is installed inside the support frame 10 and is connected to the inner clamping mechanism to achieve lateral clamping or releasing of the housing 300; wherein, the top of the outer clamping mechanism is rotatably connected to the top of the support frame 10, and the support part at the bottom of the outer clamping mechanism is provided with a gap that allows the gap between the rollers in the conveying mechanism 200 to pass through.

[0029] Understandably, the external drive mechanism 40 is connected to the external clamping assemblies 20 on both sides to drive the two external clamping assemblies 20 to simultaneously clamp or release the box on the conveying mechanism 200 inward or outward. The gap in the support part at the bottom of the external clamping assembly can be filled by the gap between the rollers in the conveying mechanism 200, so that the support part can extend into the conveying mechanism 200 to lift the box from the bottom sides of the box 300. The internal drive mechanism 50 is connected to the internal clamping assemblies 30 on both sides, and can drive the two internal clamping assemblies 30 to simultaneously apply clamping force to the sides of the box 300 inward or outward, thereby clamping the sides of the box 300.

[0030] In use, a connecting plate for connecting the robotic arm to the transport fixture 100 can be installed on the top of the support frame 10 to connect and fix the robotic arm to the transport fixture 100. When the box 300 reaches the designated position on the conveying mechanism 200, the robotic arm drops down with the entire fixture. Under the action of the inner drive mechanism 50, the inner clamping assembly 30 is controlled to clamp the box 300 from the side. At the same time, under the action of the outer drive mechanism 40, the outer clamping assembly 20 is controlled to clamp the box 300 from the bottom through the gap of the rollers. After the clamping process is completed, the robotic arm is controlled to move the box 300 away. Since the box is positioned and clamped from the bottom and the side at the same time, it can not only avoid falling during the clamping process, but also avoid the posture adjustment during the clamping process. It can improve the staggered transport, change the movement trajectory (such as changing tracks and making 90-degree turns), and complete the multi-functional transport and conveying requirements such as box stacking, making it highly adaptable.

[0031] According to the conveying and handling fixture in this embodiment of the utility model, through the cooperation of the support frame, the outer clamping mechanism, the inner clamping mechanism, the outer drive mechanism, and the inner drive mechanism, a composite handling method combining "side clamping and bottom lifting" is adopted to ensure the stability and safety of turnover boxes, especially large-load boxes, during high-speed operation and posture changes. The lateral clamping force effectively overcomes inertia and prevents slippage; the bottom support fundamentally eliminates the hidden dangers of tipping over and falling, thereby achieving extremely high positioning accuracy and handling reliability.

[0032] In some embodiments of this utility model, reference is made to Figures 1 to 12 As shown, the support frame 10 is a frame structure, including a support plate 13, uprights 11, and crossbars 12. There are four uprights 11, which are vertically installed on the support plate 13, and the line connecting the four uprights 11 forms a rectangle. The crossbars 12 are installed on the top of the uprights 11. The top of the external clamping mechanism is connected to the upper part of the uprights 11 through a bearing seat. The external drive mechanism 40 and the internal drive mechanism 50 are both installed on the support plate 13.

[0033] For example, the entire support frame 10 can be a frame structure made of profiles and iron plates, and may include four vertically arranged uprights 11, with two horizontal bars 12 symmetrically placed on top of the four uprights 11; a support plate 10 is located at the bottom of all the uprights 11. Two external clamping assemblies 20 are symmetrically arranged on the left and right sides of the support plate 13. The top of the external clamping assembly 20 is rotatably mounted on the upper part of the two uprights 11 on the same side, and the bottom of the external clamping assembly 20 is located below the support plate 13. The external drive mechanism 40 and the internal drive mechanism 50 are both mounted on the support plate 13. The external drive mechanism 40 is connected to the middle of the external clamping assembly 20, and the clamping range of the external clamping assembly 20 can be adjusted through the external drive mechanism 40. Correspondingly, the internal drive mechanism 50 is connected to the top of the internal clamping assembly 30, and the middle of the internal clamping assembly 30 is hinged to the left and right sides of the support plate 13. The clamping range of the innermost clamping assembly 30 can be adjusted through the internal drive mechanism 50.

[0034] In some embodiments of this utility model, reference is made to Figures 1 to 8 As shown, the external clamping assembly 20 includes a transmission member 21, a second support rod 22, and a bottom support rod 23. The upper end of the transmission member 21 is rotatably mounted on the support frame 10. The second support rod 22 is mounted on the lower end of the transmission member 21. There are multiple bottom support rods 23, which are installed at equal intervals on the inner side of the second support rod 22. The gap between two adjacent bottom support rods 23 is adapted to the gap between the rollers in the conveying mechanism 200.

[0035] For example, bearing seats are symmetrically installed on the uprights 11 in the support frame 10, and the top of the transmission component 21 is installed in the two bearing seats on the same side. The external drive mechanism 40 is connected to the middle of the transmission component 21, and the angle of the transmission component 21 can be adjusted through the external drive mechanism 40. A second support rod 22 is fixedly installed at the bottom of the transmission component 21. Multiple bottom support rods 23 are arranged at equal intervals along the axial direction of the second support rod 22. The bottom support rods 23 can be L-shaped rods. The gap between any two adjacent L-shaped rods is adapted to the gap between the rollers in the conveying mechanism 200, so that they can extend into the conveying mechanism 200 from the gap between the rollers and clamp it from the bottom of the box 300.

[0036] It is understandable that the upper part of the transmission component 21 is hinged to the top of the support frame 10, and the middle part is connected to the external drive mechanism 40. By controlling the external drive mechanism 40, the transmission component 21 can be driven to rotate around the hinge point at its top, thereby realizing the adjustment of the position and angle of the bottom support rod 23 at its bottom, and thus completing the clamping and release of the bottom of the box 300.

[0037] In some embodiments of this utility model, reference is made to Figures 1 to 8 As shown, the transmission component 21 includes a first support rod 211 and a first connecting plate 212. The two parallel first connecting plates 212 are connected by two first support rods 211. The second support rod 22 is connected to the lower end of the two first connecting plates 212. A first connecting rod 24 is connected between the upper ends of the two first connecting plates 212. The two ends of the first connecting rod 24 are connected to the upper part of the support frame 10 through bearing seats.

[0038] Understandably, the entire transmission component 21 can be mounted in two bearing seats on the same side via the first connecting rod 24, achieving a rotatable connection with the support frame 10. The first connecting rod 24 ensures the synchronization of the entire transmission component 21, preventing angular misalignment between the front and rear sides of the transmission component 21. The entire transmission component 21 has a simple structure and is easy to assemble and disassemble.

[0039] In some embodiments of this utility model, reference is made to Figures 1 to 8 As shown, the external drive mechanism 40 includes a first cylinder 41 and a second cylinder 42. The second cylinder 42 is arranged parallel to the first cylinder 41 and installed in the opposite direction. The fixed end of the first cylinder 41 is connected to the middle of the first external clamping assembly of the two external clamping assemblies 20, and the telescopic end is connected to the middle of the second external clamping assembly of the two external clamping assemblies 20. The fixed end of the second cylinder 42 is connected to the middle of the second external clamping assembly, and the telescopic end is connected to the middle of the first external clamping assembly.

[0040] For example, the first cylinder 41 and the second cylinder 42 are mounted on the support plate 13 in a parallel manner and with opposite installation directions. For clarity, the outer clamping assembly 20 on the right side of the support plate 13 is the first outer clamping assembly, and the outer clamping assembly 20 on the left side of the support plate 13 is the second outer clamping assembly. The fixed end of the first cylinder 41 is connected to the middle of one of the first connecting plates 212 in the first outer clamping assembly, and the telescopic end is connected to the middle of one of the first connecting plates 212 in the second outer clamping assembly. Correspondingly, the fixed end of the second cylinder 42 is connected to the middle of the other first connecting plate 212 in the second outer clamping assembly, and the telescopic end is connected to the middle of the other first connecting plate 212 in the first outer clamping assembly.

[0041] Understandably, the first cylinder 41 and the second cylinder 42 are simultaneously connected to the two external clamping assemblies 20. By controlling the simultaneous extension and retraction of the first cylinder 41 and the second cylinder 42, the two external clamping assemblies 20 can be adjusted synchronously. When the first cylinder 41 and the second cylinder 42 extend outward, the bottom support rod 23 can be controlled to move outward; when the first cylinder 41 and the second cylinder 42 retract inward, the bottom support rod 23 can be controlled to move inward, thereby clamping the box 300 located within the two external clamping assemblies 20.

[0042] To further improve the synchronization of clamping, in some embodiments of this utility model, reference is made to... Figures 1 to 8 As shown, it also includes a first synchronization mechanism 60, which includes a synchronization plate 61, a first synchronization rod 62, and a second synchronization rod 64. The synchronization plate 61 is located in the middle of the support frame 10 and above the external drive mechanism 40. One end of the first synchronization rod 62 is hinged to one end of the synchronization plate 61, and the other end of the first synchronization rod 62 is connected to the upper part of the second external clamping assembly. One end of the second synchronization rod 64 is hinged to the other end of the synchronization plate 61, and the other end of the second synchronization rod 64 is connected to the upper part of the first external clamping assembly. The bottom of the support frame 10 is provided with a central shaft 63, and the synchronization plate 61 is rotatably mounted on the central shaft 63.

[0043] For example, the central shaft 63 is installed at the center of the support plate 13, and the synchronization plate 61 is located above the support plate 13 and between the four columns 11. The synchronization plate 61 is rotatably mounted on the central shaft 63. The first synchronization rod 62 and the second synchronization rod 64 are arranged left and right. The left end of the first synchronization rod 62 is hinged to one end of the synchronization plate 61, and the right end is hinged to the upper part of the first external clamping assembly. The right end of the second synchronization rod 64 is hinged to the other end of the synchronization plate 61, and the left end is hinged to the upper part of the second external clamping assembly.

[0044] Understandably, when the first cylinder 41 and the second cylinder 42 extend outward, the first and second external clamping assemblies rotate outward. Under the action of the first synchronizing rod 62 and the second synchronizing rod 64, the synchronizing plate 61 will be subjected to a clockwise pulling force, and under the action of the central shaft 63, the entire synchronizing plate 61 will rotate clockwise around the central shaft 63. Moreover, during the rotation, the synchronization of the two external clamping assemblies can be adjusted in real time. Similarly, when the first cylinder 41 and the second cylinder 42 retract inward, the first and second external clamping assemblies rotate inward. Under the action of the first synchronizing rod 62 and the second synchronizing rod 64, the synchronizing plate 61 will be subjected to a counterclockwise pushing force, and under the action of the central shaft 63, the entire synchronizing plate 61 will rotate counterclockwise around the central shaft 63. The addition of the first synchronization mechanism 60 can further improve the synchronization of the two external clamping components 20, better realize the clamping and release of the box 300, and prevent the box 300 from tilting during the clamping or release process.

[0045] In some embodiments of this utility model, reference is made to Figures 1 to 12 As shown, the inner clamping assembly 30 includes a side clamping plate 31 and a main connecting plate 32. There are two main connecting plates 32, and the lower part of the two main connecting plates 32 is connected to the side clamping plate 31. The middle part of the two main connecting plates 32 is hinged to the support frame 10. All the main connecting plates 32 in the two inner clamping assemblies 30 are connected to the inner drive mechanism 50.

[0046] For example, the support plate 13 has symmetrical notches on its left and right sides, and the main connecting plate 32 is arranged at the notch on the same side and is hinged to the support plate 13. The top of the main connecting plate 32 is connected to the inner drive mechanism 50, and the bottom of the main connecting plate 32 is provided with a side clamping plate 31. By controlling the inner drive mechanism 50, the angle of the main connecting plate 32 can be adjusted, thereby adjusting the clamping range of the two side clamping plates 31 to adapt to the side clamping requirements of boxes 300 of different sizes.

[0047] To further improve the stability of the side clamping, in some embodiments of this utility model, reference is made to... Figures 1 to 12As shown, a second connecting rod 34 is connected to the middle of the two main connecting plates 32 in the inner clamping assembly 30. The second connecting rod 34 is rotatably mounted on the support frame 10. Auxiliary connecting plates 33 are symmetrically arranged on both sides of the two main connecting plates 32. The upper ends of the two auxiliary connecting plates 33 are connected to the second connecting rod 34, and the lower ends of the two auxiliary connecting plates 33 are connected to the side clamping plate 31. For example, the main connecting plates 32 and auxiliary connecting plates 33 on the same side can be arranged at equal intervals. The middle of the main connecting plate 32 and the top of the auxiliary connecting plate 33 are connected by the second connecting rod 34 and rotatably connected to the support plate 13. The bottom of the main connecting plates 32 and auxiliary connecting plates 33 are connected to the side clamping plate 31. When the internal drive mechanism 50 applies force to the top of the main connecting plates 32 on both sides at the same time, the main connecting plate 32, the auxiliary connecting plate 33 and the second connecting rod 34 form a complete transmission mechanism, which transmits the force to the side clamping plates 31 on both sides, and controls the two side clamping plates 31 to move synchronously in opposite or opposite directions, thereby achieving the clamping or release of the side of the housing 300.

[0048] In some embodiments of this utility model, the internal drive mechanism 50 includes a third cylinder 51, a fourth cylinder 53, a third connecting rod 52, and a fourth connecting rod 54. The fourth cylinder 53 is arranged parallel to the third cylinder 51 and installed in opposite directions. The two ends of the third connecting rod 52 are respectively connected to the fixed end of the third cylinder 51 and the telescopic end of the fourth cylinder 53. The two ends of the fourth connecting rod 54 are respectively connected to the fixed end of the fourth cylinder 53 and the telescopic end of the third cylinder 51. The third connecting rod 52 and the fourth connecting rod 54 are respectively connected to the internal clamping assembly on the same side.

[0049] For example, the third cylinder 51 and the fourth cylinder 53 are fixed to the support plate 13 in a parallel manner with opposite installation directions. The third cylinder 51, the fourth cylinder 53, the first cylinder 41, and the second cylinder 42 are parallel to each other. The third cylinder 51 and the first cylinder 41 are installed in the same direction, with their telescopic ends facing left. The fourth cylinder 53 and the second cylinder 42 are installed in the same direction, with their telescopic ends facing right. The third connecting rod 52 and the fourth connecting rod 54 are both connected to the top of the main connecting plate 32 on the same side.

[0050] It is understandable that the third cylinder 51 and the fourth cylinder 53 are connected to the two inner clamping components 30 through the third connecting rod 52 and the fourth connecting rod 54. By controlling the simultaneous extension and retraction of the third cylinder 51 and the fourth cylinder 53, the two inner clamping components 30 can be adjusted synchronously. When the third cylinder 51 and the fourth cylinder 53 extend outward, they can drive the main connecting plates 32 on both sides to rotate around their center in a top-outward and bottom-inward manner, thereby controlling the side clamping plates 31 on both sides to move inward and achieve side clamping of the inner box 300. When the third cylinder 51 and the fourth cylinder 53 retract inward, they can drive the main connecting plates 32 on both sides to rotate around their center in a top-inward and bottom-outward manner, thereby controlling the side clamping plates 31 on both sides to move outward and achieve release of the inner box 300.

[0051] To further improve the synchronicity of clamping, in some embodiments of this utility model, a second synchronization mechanism 70 is also included. The second synchronization mechanism 70 includes a synchronization block 73, a third synchronization rod 71, and a fourth synchronization rod 72. The synchronization block 73 is rotatably mounted at the center of the bottom of the support frame 10. One end of the third synchronization rod 71 is hinged to one end of the synchronization block 73, and the other end of the third synchronization rod 71 is connected to the third connecting rod 52. One end of the fourth synchronization rod 72 is hinged to the other end of the synchronization block 73, and the other end of the fourth synchronization rod 72 is connected to the fourth connecting rod 54.

[0052] For example, the synchronizing block 73 is rotatably mounted on the central shaft 63 below the synchronizing plate 61. The third synchronizing rod 71 and the fourth synchronizing rod 72 are both arranged left and right, and are located between the third cylinder 51 and the fourth cylinder 53. The left end of the third synchronizing rod 71 is hinged to one end of the synchronizing block 73, and the right end is connected to the third connecting rod 52; the right end of the fourth synchronizing rod 72 is hinged to the other end of the synchronizing block 73, and the left end is connected to the fourth connecting rod 54.

[0053] Understandably, when the third cylinder 51 and the fourth cylinder 53 extend outward, the side clamping plate 31 rotates inward. Under the action of the third synchronizing rod 71 and the fourth synchronizing rod 72, the synchronizing block 73 will be subjected to a clockwise pulling force, and under the action of the central shaft 63, the entire synchronizing block 73 will rotate clockwise around the central shaft 63. Moreover, during the rotation, the synchronization of the two connecting rods, the third connecting rod 52 and the fourth connecting rod 54, can be adjusted in real time. Similarly, when the third cylinder 51 and the fourth cylinder 53 retract inward, the side clamping plate 31 rotates outward. Under the action of the third synchronizing rod 71 and the fourth synchronizing rod 72, the synchronizing block 73 will be subjected to a counterclockwise pushing force, and under the action of the central shaft 63, the entire synchronizing block 73 will rotate counterclockwise around the central shaft 63. The addition of the second synchronization mechanism 70 can further improve the synchronization of the two inner clamping components 30, better realize the clamping and release of the box 300, and prevent the box 300 from tilting during the clamping or release process.

[0054] It should be noted that all the aforementioned cylinders can be adjustable-stroke cylinders. This fixture can quickly adapt to turnover boxes of different widths and heights, achieving compatibility of a single fixture with multiple box specifications. This greatly reduces equipment adjustment time and modification costs caused by product changeovers, and improves equipment utilization and production line flexibility.

[0055] In summary, this utility model employs a composite handling method combining "side clamping and bottom support," ensuring the stability and safety of turnover boxes, especially those with large loads, during high-speed operation and posture changes. The lateral clamping force effectively overcomes inertia and prevents slippage; the bottom support fundamentally eliminates the risk of tipping over and falling, thus achieving extremely high positioning accuracy and handling reliability. Simultaneously, this fixture can be deeply integrated with flexible actuators such as industrial robots, breaking through the physical constraints of traditional fixed conveyor lines. This allows turnover boxes to move along arbitrary trajectories, achieve precise positioning, and adjust their posture (such as lifting and rotating) in three-dimensional space, perfectly adapting to modern flexible manufacturing scenarios with complex and varied layouts and flexible processes.
